#4 cmucl/acl-excl.lisp: filesys-inode and cl-internal-real-time

I've implemented excl::filesys-inode and
excl::cl-internal-real-time. Webactions needs them.
The patch is against the Debian testing package version
1.2.33+cvs2004.01.18. I see you've restructured since
then, but I'm sure you'll be able to extract the
relevant bits :)
